A method for reducing the formation and release of hydrogen sulfide in municipal sewerage or waste water, comprising the step of:
- adding an effective amount of an agent that includes a compound selected from the group consisting of magnesium hydroxide and magnesium oxide to said municipal sewerage or waste water, wherein said municipal sewerage or waste water includes at lease one compound which can be reduced to form hydrogen sulfide.
A method of controlling hydrogen sulfide odor associated with municipal sewerage or waste water, comprising the step of:
- adding an effective amount of an agent that includes a compound selected from the group consisting of magnesium hydroxide and magnesium oxide to said municipal sewerage or waste water, wherein said municipal sewerage or waste water includes at least one compound which can be reduced to form hydrogen sulfide.
A method of obtaining a minimal level of hydrogen sulfide and of ammonia in municipal waste water or sewerage, comprising the step of:
- adding an effective amount of an agent that includes a compound selected from the group consisting of magnesium hydroxide and magnesium oxide to said municipal sewerage or waste water, wherein said municipal sewerage or waste water includes at least one compound which can be reduced to form hydrogen sulfide.
